One downside to not having much text on your slides is that the slides alone are then not as useful as a reference to attendees later.
When I do low-text slides anyway, sometimes I've used the "notes" field of the presentation program to write out complete text of a version of the speech, for my eyes only. Then I don't read the notes while presenting, but I've gone through that writing exercise, to think through the content and presentation more rigorously than is necessary to slap some headings on slides.
